The Samsung Galaxy Z Fold 4 Review

The Z Fold 4 is a good-looking and reasonably well-built smartphone that offers many of the features you’d expect from a foldable device. Its dual cameras are excellent and its battery life is impressive. However, the gap near the hinge is a source of concern. The phone is water and dust-resistant, but the frame isn’t. Its aluminum frame is polished rather than matte, and the glass on the back is a matte finish. Its camera bump is also plumper than its predecessor, possibly due to upgrades to the sensor.

Galaxy Z Fold 4

The Galaxy Z Fold 4 is the latest addition to Samsung’s Z Fold series, and it has a number of impressive features. One of these features is Flex Mode, which splits an app between the top and bottom portions of the screen. This feature gives the user an experience similar to using a laptop’s trackpad.

Samsung has redesigned its foldable screen to have a much larger display than previous models. The 6.2-inch display now has a 23:9 aspect ratio, giving the user more real estate. In addition, the bezels have been reduced to provide additional screen real estate.

Flex Mode

In Flex Mode, the phone will split the screen in half, so that the top portion becomes a viewing area and the bottom portion becomes a control panel. This is particularly useful for video-messaging apps. To enable Flex Mode, turn off orientation lock in your phone’s settings, and then fold the phone half-way. Content will shift from the bottom screen to the top. But be aware that not all apps are compatible with Flex Mode.

The camera app on the Galaxy Z Flip uses Flex Mode to allow the camera viewfinder and controls to appear on the bottom half of the screen. The camera app also supports Flex Mode, but most apps aren’t designed to support it, so you need to manually force them to be compatible with the new mode. To do this, open system settings from the app drawer and scroll down to advanced features. Once there, you can tap the slider next to the app name.

Z Fold


When it comes to cameras, the Z fold 4 has some improvements over its predecessor. The new phone features an under-display camera for selfies. The camera meshes with the screen so that it will not affect your overall view. There is still an under-display camera for video calls, but the quality is better than on its predecessor.

The camera on the Z fold 4 is capable of shooting video at up to 8K. It also offers video stabilization. The camera also has features that help it perform well in low-light conditions. Besides a dual-camera setup, the device also supports Nightography and Flex modes. While most people will probably use lower resolutions for taking photos, the Z fold 4 does offer many features and options to improve your photos.

Battery life

Samsung’s latest foldable phone, the Z Fold 4, has impressive battery life. When we tested it, we had a 53% charge after 12 hours of use. And that’s with a screen on for two hours and 45 minutes. That’s a pretty good score, and it’s not bad considering the price tag. But there is a catch. The battery takes a little longer to charge than other phones. The good news is that the Z Fold comes with a 25W charger, which is sufficient to recharge a full battery.

The battery on the Z Fold is large and powerful, with four thousand milliamp-hours of capacity. According to Samsung, this battery should give users up to 24 hours of 3G talk time or 10 hours of web browsing. However, this can vary depending on how you use the phone. Some apps tend to drain your battery more quickly than others, so you should pay close attention to which apps are using up your phone’s battery.


The Z Fold 3 features three cameras on the back, located in the oblong bump on the back of the device. One is a 12MP wide-angle lens, while the other two are 12MP telephoto lenses with OIS. All three cameras are equipped with dual-pixel PDAF technology. The telephoto lens is also equipped with an SK Hynix Hi-1337 sensor for superior imaging.

The price of the Z Fold 3 was reportedly reduced by over $100 from its predecessors. The company has been making a push to make its folding phones affordable to everyone. The new model launched in August and is priced less than its predecessor. The 256GB and 512GB variants cost $1799 and $1999, respectively.
